Sportpark Marie Pampoen in Curaçao rents out football, bolas and multi-purpose fields to clubs, teams and facilitators. Bookings were kept by hand in Excel, and coordination had to be done manually by sports park managers. Together with the board, we shaped SMP Online: one system for reservations, day and night rates, client discounts and billing, now used for daily operations.

It handles more than 80 reservations a month, and the board no longer spends any time keeping field occupancy in sync.
